It is a widely established truth that the quality of kitchen tools greatly improves the cooking experience. A hollow edge knife, typically, the Santoku Knife, is one of the greatest examples of an ideal kitchen tool. This Japanese knife is designed not just for functionality but for precision and ease, making it a good choice for both chefs and home cooks. If you want to buy a new hollow edge knife, especially the hollow edge Santoku knife, knowing what makes the hollow edge Santoku knife unique can help you make a smart choice. This guide will help you learn some important features about hollow edge Santoku knives and how to maintain your high-quality Santoku knives.

What is a Hollow Edge Santoku Knife?

Before getting close to hollow edge Santoku knives, let’s start with what a hollow edge knife is. A hollow edge knife usually features small indentations along the blade, typically known as “Granton edges”. These indentations can create air pockets while cutting, which can help prevent food from sticking to the blade and let you make thinner slices.

The Santoku knife is a typical example of hollow edge knives. The Japanese term “Santoku” can be translated into “three virtues” in English, which can be interpreted to refer to slicing, dicing, and mincing—the three primary tasks that this knife performs with exceptional ease. The Santoku knife is usually crafted with a broad blade and a sharper curve at the tip, which differs from the traditional chef's knife. This design can provide a more manageable balance and a lighter weight, making it perfect for a range of tasks. Developed in the mid-20th century as a home kitchen alternative to some specialized knives used in professional Japanese kitchens, the Santoku knife quickly became popular for its utility. 

Important Features of Hollow Edge Santoku Knives

Knowing what makes a hollow edge knife different can help you to make a good choice-whether to buy or how to choose. There are several important features that you can focus on.

1. Strategically Arranged Indentations

The hollow edge design of a Santoku knife can be what you first focus on. Consider the depth and spacing of these indentations.  Deeper, more widely spaced grooves generally make it easier for food to slide off the knife and reduce drag.

2. High-carbon Steel or Stainless Steel Materials

Except for the hollow edge design, the blade material is the factor that you should not overlook for any knife. High-carbon steel and stainless steel can be the recommended materials for hollow edge Santoku knives, as they can usually offer sharpness or rust resistance. Ceramic is also an option but knives made of ceramic should be carefully patiently.

3. 15-20 Degrees of the Sharp Cutting Angle

A hollow edge Santoku knife should have a sharp cutting angle. A Santoku knife with a cutting angle over 20 degrees may be too large. Try to find a blade with an angle of between 15 and 20 degrees. It will be better if you manage to find a blade sharpened to less than 15 degrees.

Cleaning: Always wash your knife with warm soapy water immediately after use to remove food residues and prevent bacterial growth. Avoid using the dishwasher as the harsh chemicals and heat may damage the fine edge of the blade. After washing, dry it thoroughly with a soft cloth to prevent water spots and potential rusting.

Storage: Proper storage is key to preserving the sharpness and quality of your knife. Use a knife block, magnetic strip, or a sheath to protect the blade. These storage methods help maintain the knife's edge by preventing unnecessary contact with hard surfaces and other utensils. Additionally, storing the knife in a visible and accessible place will keep it handy for use while ensuring it is safe from accidental damage.

Sharpening: Regular honing is necessary to maintain the blade's sharpness. You can use a ceramic rod or a diamond stone. They are usually gentle on the delicate edge while effective enough to smooth any burrs. Sharpening your knife every few uses will keep it in the best condition for precise cuts.
